The eigenvector

WebSep 18, 2024 · The PCA algorithm consists of the following steps. Standardizing data by subtracting the mean and dividing by the standard deviation. Calculate the Covariance matrix. Calculate eigenvalues and eigenvectors. Merge the eigenvectors into a matrix and apply it to the data. This rotates and scales the data. Webeigenvectors: x = Ax De nitions A nonzero vector x is an eigenvector if there is a number such that Ax = x: The scalar value is called the eigenvalue. Note that it is always true that A0 = 0 for any . This is why we make the distinction than an eigenvector must be a nonzero vector, and an eigenvalue must correspond to a nonzero vector.
